Share 'Should i throw these discs or keep them???'

I have a new Worlds 08 Zone ESP and a new Worlds 08 Quarter K II from Discwing. The only reason i would consider not throwing them is in hopes that they will be worth money one day. Since i know nothing about how or what discs gain value i would like your opinion. Other then the money factor i would love to throw them so let me know please.
